Many-to-Many Singing Technique Conversion

We focus on singing technique conversion in this demo page.
The following are the audio samples of Fig. 2(b) in the paper.

The audio files below are all converted from Mel-spectrograms using Griffin-Lim.
Therefore, the audio "original Mel-spectrogram" are the upper bounds of the audio quality for each conversion.

We first give examples of each singing technique

Again, these samples are obtained by inverting from their Mel-spectrograms to audio
